Boar Miniature male ileum, SV40 transformed

Epitheloid cell line derived from the ileum of an adult histocompatible miniature male boar. Transformed by SV40 plasmid pSV3-neo. Electron microscopy analysis shows evidence of microvilli and desmosomes connecting cells. The cells were found to co-express cytokeratin 18 specific of simple luminal epithelial cells and vimentin associated with a mesenchymal origin. Susceptible to Transmissible Gastro-enteritis (TG) virus.

Studies of epithelial cell differentiation.

DMEM + 4mM Glutamine + 0.024IU/ml Insulin + 10% Foetal Bovine Serum (FBS).
